4. Inspection Procedures
CAUTION: INSTRUCTIONS AND PROCEDURES IN
THIS SECTION MAY INVOLVE PROPELLER
CRITICAL PARTS. REFER TO THE
INTRODUCTION CHAPTER OF THIS MANUAL
FOR INFORMATION ABOUT PROPELLER
CRITICAL PARTS. REFER TO THE
ILLUSTRATED PARTS LIST CHAPTER OF THE
APPLICABLE OVERHAUL MANUAL(S) FOR THE
IDENTIFICATION OF SPECIFIC PROPELLER
CRITICAL PARTS.
The following inspections are made on a regular basis, either
before flight, during the 100 hour inspection, or if a problem
is noted. Possible corrections to problems discovered during
inspections, additional inspections, and limits are detailed in the
following inspection procedures.
A. Blade Damage
Refer to Blade Repairs section in the Maintenance Practices
chapter of this manual for information regarding blade
damage.
B. Grease or Oil Leakage
NOTE: A new or newly overhauled propeller may leak
slightly during the first several hours of operation.
This leakage may be caused by the seating of seals
and O-rings, and the slinging of lubricants used
during assembly. Such leakage should cease within
the first ten hours of operation.
(1) Leakage that persists beyond the first ten hours of
operation on a new or newly overhauled propeller, or
occurs on a propeller that has been in service for some
time will require repair. A determination should be made as
to the source of the leak.
(2) The only leakage that is field repairable is the replacement
of the O-rings in the cylinder for -3 and -6 propellers,
the diaphragm on -7 and -8 propellers, and the gasket
between the cylinder and engine. For additional
information, refer to the Oil or Grease Leakage section in
the Testing and Troubleshooting chapter of this manual.
